Reveton is a piece of ransomware where when it gets into a system, it falsely accuses victims of downloading images of child abuse or downloading copyright-protected content before demanding a fine to unlock computers.

“Ransomware is most commonly spread via drive-by downloads and Reveton especially has been seen working with some of the most notorious exploit kits available today,” Kujawa said. “Disabling Java Script and keeping all of your plugins and browser as up to date as possible will help deter any attempts for Ransomware to steal your system and maybe even your money.”
